HEATING SYSTEM FOR COL'VIPARTMENT-CARS.

Specification of Letters Patent.

Patented Mar. 21, 1911.

Application filed .Tune 7, 1909. Serial No. 500,478.

To all 'whom 'it may concern:

lBe it known that I, EGBERT H. GOLD, a citizen 'of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Heating System for Compartment-Cars, of which the following is a specification. l

My vinvention relates to a heating system particularly' designed and intended for heatwhich does notinvolve an undue multiplication of valves and controllers, and which,

Ain consequence is relatively economical' to :inst-all and easily understood in its operationbythe attendant having` charge of the same.v 4

While the novel arrangement of the valves and controlling means 1n a heating system which forms the special matter of this application might be employed with some advantage, in various systems of different types, 1t 1s partlcularly designed for use and 1s of particular value when used in an at- `mospheiic pressure system of heating; and

in this regard' it is one of the objects of my invention to adapt the well known atmospheric pressure system or vapor system of car heating tothe special requirements and needs of compartment cars. Y

A- further object ofthe invention `is to provide a heating system for compartment cars' which, by. proper regulation of the valves, may be made to heat the car as a whole sufficiently for moderate weather and sufficiently to keep the water pipes and the Alike from freezing in any sort of weather,

no matter how cold.; which, however, will supply additional heat to any or all of the compartments that may need the same; and which when desired will supply heat to any 'of the compartments separately and in varying degrees, as desired, from the unitary system-which 1s connnon to the entire car. The invention has for further objects such new and improved constructions in heat-ing systems and in systems for heating` railway compartment cars, as will be described in this specification and specifically set forth .in the claims appended thereto.

The invention in a preferred embodiment is illustrated in the accompanying drawings, whereini Figure l is a fragmentary sectional plan of a railway car illustrating an arrangement of heating coils, valves and automatic controllers in accordance with my invention, the arrangement of the heating coils being somewhat vdiagrammatic for the purpose of clearness of illustration. Fig. 2 is a sectional plan through two of the four-way vvalves employed. Fig.- 3 is a vertical section on line 3-3 of Fig. 2 looking inthe direction of the arrows. Fig. 4 is a vertical section illustrating an automatic controller orvapor regulator suitable for the type of `heating system illustrated in the preceding figures.

Like characters of reference indicate like parts in the several figures of the drawings.

Referring to the drawings, A represents a common form of compartment car divided into a plurality of compartments, B, B, B2, B3, B4, which open upon an aisle C.

' a are the seats.

D is asteam train pipe which runs the length of the' train and receives steam at relatively high', though variable, pressure `from the locomotive.

For heating thecar as a whole, I preferably provide a coil of radiating pipes E which preferably runs the length of the car through all of the compartments. This coil,

when supplied with steam, serves to keep the car at a moderate temperature when the weather is not too cold and also serves, in all weathers toK keep the water pipes land the like in the car from freezing up. This coil is fed from the .train pipe preferably through a vapor regulatorl F and a fourway valve G, of constructions to be described hereafter, this arrangement being such that steam may be admitted to or shut oi from the coil as desired, and when ad- ,mitted will be maintained inthe coil at substantially atmospheric pressure. For the purpose of supplying additional heat to the compartments separately, in accordance with the'desires of the several occupants, or to so supply the compartments with heat when it is not desired to heat the car as a Wholef-that is when coil E is ont out-I provide the several compartments-With supplemental radiators H, H, H2, H3 and H4. These radiators are supplied fromv and dis- 5 charge into a pipe J Which may be termed a supply pipe or a supply circuit and Which, as shown, preferably takes steam from the train pipe D through a vapor regulator F, the return end of said circuit leading to the thermostat chamber of said controller, as Will be hereafter described. The several supplemental radiators H, H, etc., are connected both at their inlet ends and also their discharge ends through a plurality of four'- Way valves K,K, K2 and K3, Which are ot such construction and so. arranged in the l supply circuit J that any of said radiators may be supplied with steam or may be closed, as desired, the steam being obliged to pass in series through such of the radiators as are open. l

i The four-way valves G, K, K', etc., are all alike. the arrangement of the valves employed in the, controlling circuit J is shown in Figs. 2 and `Referring rst to Fi 2, the valve consists of a casing l0, divide into fourchambers, 11, 12, 13 and 14 by Webs 15,A 16, 17 and 1,8. The valve piece consists of the upper andl lower disks 19 and 20 and the vertical Web 21, these parts being arranged upon a stem 22 provided With a handle 23. llithin the bonnet 24 is a spring 25y which bears against the upper disk 19. The lower disk has the drip opening 26 Which'registers With the opening 27 -in the bottom of the case when web 2l is turned to the dotted line position of Fig. 2,fthat is', When the radiator is bypassed. This ,descriptionapplies to all ot' the four-Way valvesl of the system. It Will be seen that supply circuit J leads into p chamber 11 of one valve and connects chamfbcr 12 of said valve with chamber 11 of the 45 :next valve;

\ `Supposing the left hand valve of Fig. 2 to be the valve K of Fig. 1,.the inlet end ot radiator H leads from' chamber 14 and the discharge end of the radiator to chamber 13. E1) The vapor regulators F, F', if used', are Vtl1' e` sa'1ne in construction and may be the familiar form of vaporgregulator shown in Fig. 4. A- casing 28 is divided by web 29 to form a high vpressure chamber 30 and a 55 10W pressure chamber 31, communicating by port 32, controlled by valve 33, provided with a stem 34, attached to a bell crank 35, vpivoted at 36 to .a Web 37, .the other-arm,oatl

the, bell' crank being connectedyyith the O'peratingrod 38 of the thermostat39,the op`ffe -erating rod and thermostat being-locatcd inI a'suitable casing 40. Supposin'gfthis controller to be the controller F of Fig.- 1,'it vwill be connected With train pipeD by the rhort pipe 41 which leads to chamber-"BOQ' The construction of these valves and y vpartments.

`The inlet end of supply circuit leadsfrom chamber 31 and the discharge end of supply circuit J to the interior of casing 40. )is this form of thermostatic controller is Well known, I have described only such parts as are neccssaryfor the understanding of the function ot' the controller in theheating system of this application. l

The operation of this system ot heating is as Afollows: lVhenever the weather is cold,v coil E will be in operation. Its thermostatic controller F, if used, Will maintainv the steam in the coil at substantially atmospheric pressure. The heat given out Willl -j be sufficient to keep the Water pipes and the like located in the car from freezing. In moderate weather this coil will be ordinarily suiiicient to heat the compartments With-- out employing the supplemental coils Thev interposition of the four-Way valve by,- passes `the steam which goes through the controller to the thermostatic member ot the. controller, in case valve G is closed andcoi E is cut out, so that there is nodanger'of L freezing up the thermostat. 'When addi-y 90 tional heat isY required for anycompartmeht, its ii'ourway 'valve'may be set to the4 ful line position of Fig. 2, and .in suchfca-se steam fromv4 supplyl .circuit must f'passv through the coil in such compartment lhej-1295 fore it can proceed to the 'next compartment' coil or through supply circuitafvfI to they ther# mostatic chamber of controller F",'.a$ the case may be.v This arrangement insures the lling With steam of all of the coils thatina'y 100 be open. p All of thesupplemental coils may thus be controlled by a single thermostatic controller F" which operates in. the cus-A tomary manner, if such a controller be used that is, steam Will enter the high pressure 1.05' chamber '30 of the controller, pass intocham ber 31, past valve 33, so long as the latter is open, and `thence through the radiatorand into contact with thermostat 39. The latter is expandedl by contact with -steam and this'A 11o closes or throttles valve 33, so that in eli'ect onlyvso much steam is allowed to 'pass said valve as Will keep the-radiators illedaat at mospheric pressure. When the valvevot any coil is set so as .'to. 11,5 close the coil, the d rip openings 26, 27 are brought to aregister so as to afford an out-4 let for Water of .condensa-tion and steam by'- passes through chambersl 11 and 12.

The supplemental coils may be used even when coil E is not under steam, as, for eX= ample, in Warm Weather When -it is not advisable to heatthe entire car, but heatis requiredv :t'or some one or 'more offthefcom- It Will loe-'seen that the above described system has ,considerable capacit-y for arbitrary regulation in order to meet special requirements of compartment cars. After the arbitrary regulation has been made by a 130 proper setting of the valves, the required supply of steam will be maintained auto- `matically iit' an automatic supply regulator other valves, and with a -system of piping ,Y in each of said compartments, a Supply pipe which is comparatively simple. 'The result is that the system is economical to install and simple and easily'comprehensible in its operation. No steam goes to waste. Suitible radiators may be employed for heating the aisles and other portions ot the car. These have not been shown. as they form no part of my present invention.

I do not limit myself to'the particular devices, constructions and arrangements herein shown, as'moeiihcations might be devised which would come within the scope of my invention, as delineddiy the claims.

In thisl applicatidn I do not claim broadly the combination of a primary radiator such as the coil E and one or more supplemental radiators, such as the coils H, H. etc., as this combination is broadly claimed in my pending application, Serial No. 464,057, 'tiled November Q23, l908.`
